[Compliance of the lung-thorax system in pregnancy complicated by pre-eclampsia].

Compliance of the lungs and thorax was studied in 65 pregnant women during cesarean section. The measurements were carried out in a group of healthy controls and in patients with preeclampsia. The detected changes indicated increased rigidity of the lungs even in normal pregnancy. Comparison of the results indicates an appreciable increase of rigidity of the lungs in patients with preeclampsia, this permitting us to regard it as a status involving interstitial pulmonary hyperhydration.
